Home Improvement - The Bathroom

The apartment we are renting is small for us. We have Stuff. We like our Stuff. We are Stuff people. And over the past 12 days we have been accumulating more Stuff. Mostly it has been in an effort to organise and make the small space we have work for us. The kitchen and bathroom had inadequate spaces for our Stuff.
The bathroom had one small towel rack large enough for a hand towel and a facecloth, and two corner shelves of wire designed for clean towel storage I think; but only if the towels are the minicule type they give you at tourist class hotels.
The bathroom is about half the size of our laundry room at home so there is not a lot of room for anything else, but we did shoehorn in 2 stackable shelf units 12x12 inches square and 6 feet high for the bathroom Stuff. Thankyou Home Depot.
Towel racks were a problem. No wall space for a start. Peter is an Engineer at heart though and we had several tries at solutions.
1. We looked for an over the door towel bar but no one makes those it seems.
2. We attempted to make an over the door towel bar using 2 over the door hooks and a dowel between them. We discovered that the door wouldn't close, and the door was so narrow it only allowed one towel anyway.
3. We tried to use the above device on the top of the shower stall frame. Frame too thin to hold the hooks properly, and the dowel would fall off when the towels were touched. We used the over the door hooks for our bathrobes in the bedroom and abandoned the dowel idea altogether.
4. Yesterday at a yard sale Peter scored one of those chrome, floor to ceiling spring loaded towel racks with the rings that everyone had in the '70s. Perfect. Compact. Holds 4 towels. Unfortunately we have a suspended ceiling in the bathroom and the ceiling tiles would not stay put to hold it in place. Hmmmmm.
5. Today, under the heading "Box, what box?" Peter erected the "floor to ceiling" rod as a "wall to wall" rod, proving once again that my sweetie is at 90 degrees to the rest of the world.
Yes, this is the whole bathroom. Shower is behind the door.
